What are Fire Extinguishers?
Fire extinguishers are portable firefighting devices designed to control or extinguish small fires before they escalate. They are one of the most recognisable pieces of fire safety equipment and, when used correctly by a trained person, can prevent a minor incident from becoming a life-threatening emergency. There are several classes of fire extinguisher, each designed to tackle specific types of fire, including water, foam, CO2, dry powder, and wet chemical variants. Understanding the different types of fire extinguishers and their appropriate applications is essential to effective fire safety planning.
In the UK, the supply, installation, and servicing of fire extinguishers is governed primarily by BS 5306, which sets out the requirements for selection, commissioning, and ongoing maintenance. The Regulatory Reform (Fire Safety) Order 2005 places a duty on the responsible person of any non-domestic premises to ensure that appropriate firefighting equipment is provided, accessible, and kept in good working order. London City Fire supplies, installs, and services extinguishers across all property types in London, ensuring the right equipment is in the right place for the specific risks present in each building.
It is worth noting that fire extinguishers are not a substitute for a full fire safety strategy. They work best as part of a broader framework that includes fire alarm systems, fire doors, emergency lighting, and regular fire risk assessments. London City Fire takes a holistic view of fire protection, helping clients understand how each element of their fire safety provision fits together.
Why are Fire Extinguishers Required?
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for any non-domestic premises must carry out or commission a fire risk assessment and implement appropriate fire safety measures based on its findings. In most cases, this will include the provision of suitable firefighting equipment, with portable fire extinguishers being the most common requirement. The Fire Safety Act 2021 has further strengthened these obligations, particularly for multi-occupied residential buildings, meaning landlords, managing agents, and building owners face greater scrutiny than ever before. Failure to comply can result in enforcement action by the local fire and rescue service, including prohibition notices that prevent a building from being occupied.
Beyond legal compliance, there is a straightforward duty of care to consider. Providing correctly specified and properly maintained extinguishers gives building occupants a practical means of responding to a small fire in its earliest stages. A well-maintained extinguisher that fails to operate when needed is just as dangerous as having no extinguisher at all, which is why annual servicing in accordance with BS 5306-3 is not optional. London City Fire ensures every extinguisher it services is fully operational and clearly labelled, so your building stays compliant and your occupants stay safe.
What Does Fire Extinguisher Servicing Involve?
London City Fire provides a complete fire extinguisher service covering supply, installation, and annual maintenance. When we first attend a property, our engineers carry out an assessment of the premises to determine the correct type, number, and placement of extinguishers based on the fire risks identified. This takes into account factors such as the size of the building, the activities carried out on-site, the materials present, and the layout of escape routes. Once the correct specification is agreed, extinguishers are supplied and installed in compliant positions with appropriate signage, ready for immediate use.
Annual servicing visits follow a structured process in line with BS 5306-3. Our engineers inspect each extinguisher for physical damage, check the pressure gauge, verify that safety pins and tamper seals are intact, and confirm that discharge instructions are legible. Where required, extinguishers are recharged or replaced. At the end of each visit, clients receive a service record documenting the condition of every unit, the work carried out, and confirmation of compliance. If you are considering purchasing extinguishers directly for a smaller site, you can also buy fire extinguishers through London City Fire, with guidance on the correct selection for your needs.

Who Needs Fire Extinguishers?
In practice, almost every non-domestic building in London requires fire extinguishers as part of its fire safety provision. This includes commercial offices, retail units, warehouses, hospitality venues, schools, healthcare facilities, and places of worship. Landlords of residential blocks, including houses in multiple occupation and purpose-built apartment buildings, are increasingly required to provide firefighting equipment in communal areas as a result of the Fire Safety Act 2021 and updated guidance from the National Fire Chiefs Council. Property developers and managing agents working across London’s diverse building stock will often need extinguishers specified and installed as part of a broader fire safety package, alongside services such as fire alarm installation and fire door maintenance.
Small businesses are not exempt from these requirements. Even a single-room office or a compact retail unit typically requires at least one correctly specified extinguisher, positioned accessibly and serviced on schedule. The size of the premises affects the number and type of extinguishers required, rather than whether they are needed at all. London City Fire works with businesses of all sizes, from single-location independents to large multi-site operators, ensuring that every client has the right provision in place and the documentation to prove it at any inspection.

Frequently Asked Questions
Q: “How often do fire extinguishers need to be serviced?”
A: Fire extinguishers must be serviced annually in accordance with BS 5306-3. In addition to the annual inspection, most extinguishers require an extended service every five years and replacement or overhaul at the end of their recommended lifespan. Regular servicing ensures they will operate correctly in an emergency and keeps your property compliant with UK fire safety legislation.
Q: “Who is legally responsible for fire extinguisher maintenance?”
A: Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a premises is legally obligated to ensure that firefighting equipment, including fire extinguishers, is maintained in an efficient state and good working order. In most commercial properties this is the employer or building owner, while in residential blocks it is typically the landlord or managing agent. Appointing a competent fire safety company to carry out annual servicing is the most reliable way to meet this duty.
Q: “Do I need fire extinguishers for a small business?”
A: Yes, in most cases even small businesses are required to have appropriate firefighting equipment in place. The specific number and type of extinguishers will depend on the size of your premises, the activities carried out, and the findings of your fire risk assessment. London City Fire can advise on the correct specification for any size of business and ensure everything is installed and documented to the required standard.
Q: “What happens if my fire extinguishers are not serviced?”
A: Failure to maintain fire extinguishers can result in enforcement action by the local fire and rescue service, including improvement or prohibition notices. It may also invalidate your building insurance and, critically, leave occupants without functioning firefighting equipment in the event of an emergency. Keeping extinguishers properly serviced is both a legal requirement and a fundamental part of your duty of care to everyone in the building.
Q: “Are all fire extinguishers safe to use indoors?”
A: Not all extinguisher types are suitable for every environment. For example, dry powder extinguishers are generally not recommended for indoor use in occupied buildings due to the risks associated with inhaling the discharged material. CO2 extinguishers are commonly used for electrical fires but must be handled carefully in confined spaces. If you have concerns about the safety profile of different extinguisher types, our guide on whether fire extinguishers are toxic covers this in more detail, and our engineers can advise on the most appropriate choice for your specific setting.
